Lot 485: The inventor of a dentist's drill.

Description:
The inventor of a dentist's drill. A man in ordinary dress operates his invention with a foot pedal. A wheel draws or releases two strands of wire or cord that make a thicker line rotate that extends out from the top of the pole. It comes to a point. This is a primitive drill. It is held by a man [the inventor] who holds a small dental mirror in his other hand. This is likely to be James B. Morrison, the inventor of this drill in 1871. It is an important milestone in the development of modern dentistry. By McDonald, South Bend Indiana.
